Abstract:With the development and operation of civil aircraft, aircraft main manufacturers need to simultaneously develop and verify the Preliminary Master Minimum Equipment List (PMMEL) item to improve the reliability of civil aircraft dispatch and obtain approval from the Administrator. In order to manage the relevant data generated during the development and verification of the PMMEL item through a standardized method, the development and application of relevant development platforms are urgently needed. This article first studies the implementation process and industry requirements of the PMMEL item development, and clarifies the data management requirements of the PMMEL development and verification process based on the ATA2300 standard. On this basis, the PMMEL development platform was constructed. After a complete system functional test to ensure the reliability of the platform, the actual PMMEL project data was further used to test for proof of concept, so as to prove the compliance and matching degree of the platform to the business. The results show that the development and verification data of the PMMEL project are further standardized through the construction and use of the platform, which can lay an important data foundation for the compilation of the later operation support manual. The continuous operation of the company will carry out further intelligent expansion.
